title: A scientific and psychosocial environmental investigation tool: the Meeting, Understanding, Surveillance, Toxicology, Evaluation and Reporting (MUSTER) model.
abstract: BACKGROUND
  Although there is a wealth of information on hazards in the environment and robust systems for measuring environmental pollutants, there is limited guidance for practitioners in any field of health which addresses the psychosocial element of environmental investigations. Investigating environmental concerns is, however, necessary. It is possible that health may be affected by a previously unknown contaminate or may potentially be affected if action is not taken.
  
  
  METHODS
  To address this, a model for the integration of scientific and psychosocial considerations into a systematic, complainant centred approach for practitioners undertaking environmental investigations has been developed for use by public health professionals, environmental health officers, occupational health professionals, and general practitioners, among others. The process involves Meeting and interviewing individual complainants, Understanding individual and local concerns, reviewing Surveillance and Toxicological data, Evaluating findings, and Reporting on findings-the MUSTER model.
  
  
  RESULTS
  The MUSTER model proposes a method of investigation at an individual level which addresses physical, and psychosocial concerns. It is presented with real life case studies which demonstrate the importance of addressing each aspect. The model incorporates what is already known about health and environmental investigations but presents this in an easy-to-remember mnemonic. While the model has been derived from public health investigations its application is equally suited for any practitioner undertaking a health related environmental investigation.
  
  
  CONCLUSIONS
  The MUSTER model should be disseminated widely so that there is a robust, evidence based and consistent approach to environmental investigations which satisfies complainants, enhances practitioner knowledge base, and improves communication.
